what is being conveyed by the speaker. It is not simply the assignment of words to simple diagrams or categories, but also involves evaluating the meaning of a sentence according to the rules of syntax drawn by inferences made from each word in the sentence. This evaluation of meaning is what makes parsing such a complex process. When speech or text is being parsed, each word in a sentence is examined and processed to contribute to the overall meaning and understanding of the sentence as a whole. <br /> </p><p>It occurs as the language is being processed, examining both the past and present stimuli to allow understanding of future concepts. When a sentence is read, the reader decides which categories the words belong in. These categories include basic grammatical components,(such as agent, proposition, patient) that are assigned based on what is inferred. These categories are very basic, simple enough that a computer can parse them if enough grammatical rules and roles are known. </p><p>However, parsing cannot just rely on simple grammatical rules as quite often, these thematic categorical components can be assigned to multiple categories or take on multiple meanings that drastically change the meaning of a sentence. This is part of what causes parsing to be so complex as it must go past the basic grammatical understanding of a word or a sentence and apply the correct meaning to it. </p><p>Parsing allows the reader to make these decisions, based on cues obtained from the words previously read in the sentence and the conclusions that can be drawn from these words. It takes the meaning drawn from what was read previously to allow understanding of what is currently being read.

This initial comprehension must be made before further and deeper inferences can be parsed. As a sentence is being spoken or read, roles are assigned to every noun phrase by using role assignors such as verbs. The verbs being assigned determine which roles need to be filled in a sentence, depending on which noun phrases are used. The primary decisions in parsing are based on the lowest "cost" in the sentence system in liking roles and noun phrases together. This means that the decisions regarding assignment to categories are based on the lowest amount of rules broken. <br /><br /> The thematic roles focus on the lexical information being presented. They rely on interpreting the words semantically in a sentence. It allows the linkage and coordination of both the semantic and discourse information as well as lexical and syntactic information (Christianson, 2001). <br /> </p> <div class="mw-heading mw-heading4"><h4 id="Semantic_Features">Semantic Features</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=4" title="Edit section: Semantic Features" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=4" title="Edit section's source code: Semantic Features"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Semantic features are associations that are directly affiliated with a particular word or idea. These associations may be conscious or subconscious. For example, a person thinks of an apple, they might also think of the color red, a worm or a tree. If a person thinks of a bird, then flying, feathers, and nest, may come to mind, as they are semantic features related to birds. <br /><br /> </p><p><br /> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Appleassociations.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikiversity/en/thumb/b/b6/Appleassociations.jpg/220px-Appleassociations.jpg" decoding="async" width="220" height="209" class="mw-file-element" srcset="//upload.wikimedia.org/wikiversity/en/thumb/b/b6/Appleassociations.jpg/330px-Appleassociations.jpg 1.5x, //upload.wikimedia.org/wikiversity/en/thumb/b/b6/Appleassociations.jpg/440px-Appleassociations.jpg 2x" data-file-width="866" data-file-height="822" /></a><figcaption> Semantic associations with the world APPLE .</figcaption></figure> <p>When parsing occurs of a sentence or phrase, the parser uses these semantic features of a word to draw inferences about the meaning of a sentence. This is crucial to understanding a sentence as sometimes examining thematic roles is not enough. This is especially true with common phrases or slang that doesn't always mean what the direct thematic roles suggest. An example of this would be, "Jane kicked the bucket." Parsing that sentence without knowing the correct semantic features would cause the reader to believe that Jane actually knocked over a bucket with her foot. However, knowing that this phrase is also semantically associated with dying, the reader can parse the sentence correctly. <br /> <br /> </p><p>Semantic features of sentences don't have to be so obvious however. Sometimes when a sentence is vague or could have multiple meanings, parsing relies on the associations with the words to derive the correct meaning. An example of this would be in the sentence, "Rover barked when someone entered the house." The semantic features in this sentence suggest that Rover is a dog. This is not stated in the sentence, thus Rover could be a cat, a seal or even a person. However due to these semantic features (in this case, the pronoun and the use of the word barking), the reader can correctly infer that Rover is a dog. <br /> <br /> </p><p>Knowing the overall meaning and associations in a sentence allows the cotent to be understood much faster, thus decreasing the time it takes to parse a sentence. However, sometimes errors can be made because of relying on semantics too much during parsing of a sentence, causing the wrong inferences to be drawn. An example of this is a long time riddle: "A plane crashes on the border between Canada and the United States. Where do they bury the survivors?" The semantics associated with a plane crash and burying suggest that victims should be buried. This leads to the wrong meaning being derived and the parsing of the sentence to be incorrect. However, even with these errors, relying on the semantic features of a sentence allows parsing to be completed much more efficiently. <br /> </p> <div class="mw-heading mw-heading4"><h4 id="Probabilities">Probabilities</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=5" title="Edit section: Probabilities" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=5" title="Edit section's source code: Probabilities"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Probdist.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/eb/Probdist.png/220px-Probdist.png" decoding="async" width="220" height="100" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/eb/Probdist.png/330px-Probdist.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/eb/Probdist.png/440px-Probdist.png 2x" data-file-width="687" data-file-height="312" /></a><figcaption>The probabilities affect what meaning we extract from a sentence.</figcaption></figure> <p>The probability of a particular meaning of a word being associated with a particular sentence directly drives parsing.

For example, "Visiting relatives can be such a nuisance."

Parsing is the process of dividing this. He suggests that sentences have both a simple and a deep structure. The deep structure, which is the meaning of a sentence, is the most meaningful and abstract level of representation of a sentence. Parsing is critical to determining this deep structure. <br /><br /> Chomsky also created the tree diagrams that serve as a visual representation for how parsing occurs. For an example of a tree diagram, you can click <a rel="nofollow" class="external text" href="http://www.wellnowwhat.net/linguistics/bhg/the-man-hit-the-ball.png">Here.</a> <br /><br /> Another example is illustrated below.<br /> <span class="mw-default-size" typeof="mw:File"><a href="/wiki/File:Basic_english_syntax_tree.svg" class="mw-file-description" title="Basic english syntax tree"><img alt="Basic english syntax tree" src="//upload.wikimedia.org/wikipedia/commons/thumb/2/23/Basic_english_syntax_tree.svg/150px-Basic_english_syntax_tree.svg.png" decoding="async" width="150" height="172" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/23/Basic_english_syntax_tree.svg/225px-Basic_english_syntax_tree.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/23/Basic_english_syntax_tree.svg/300px-Basic_english_syntax_tree.svg.png 2x" data-file-width="150" data-file-height="172" /></a></span><br /> Parsing uses these strategies in top down and bottom up parsing. Top down, often called conceptually driven parsing, moves from the top of the tree diagram. It is guided by higher level previous knowledge, which in turn affects the lower level processes. Bottom up processing, or data-driven parsing, is when parsing decisions are made from the bottom of the tree diagram; it is when the parsing decisions are guided by only the features of the sentence itself, driven by the knowledge that is obtained at that given time. The parser starts with the most basic elements, then moves to the more complicated (Ashcraft, 2006). </p> <div class="mw-heading mw-heading2"><h2 id="Theories_of_Parsing">Theories of Parsing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=11" title="Edit section: Theories of Parsing" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=11" title="Edit section's source code: Theories of Parsing"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are two main theories for parsing of the English language. <br /> </p><p>1) Garden Path Model: Minimal Attachment<br /> </p><p>2) Constraint Satisfaction Models<br /> <br /> </p> <div class="mw-heading mw-heading2"><h2 id="Garden_Path_Sentences">Garden Path Sentences</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=12" title="Edit section: Garden Path Sentences" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=12" title="Edit section's source code: Garden Path Sentences"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The Garden Path model is a dominant theory in about how people are able to parse words together to interpret the meaning of statements. The title of the theory is based on a metaphor about being led down the wrong path. In regards to psycholinguistics, a person can be led down the wrong path while reading a sentence when they make inaccurate assumptions about the context of the noun phrases. The reader is not aware that they are being lead down the wrong path. At the beginning of the sentence, or the path, the reader is under the impression that they are proceeding in the right direction with the syntactic structure and making the correct assumptions as they are reading. Then suddenly, new information presented later on in the sentence causes the reader to fall down the rabbit hole. This new information causes confusion because, up until that rabbit hole, the reader assumed they were correct in their perception of the garden path. <br /> </p> <p><br /> </p><figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Chatsworth_maze.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/55/Chatsworth_maze.jpg/220px-Chatsworth_maze.jpg" decoding="async" width="220" height="138" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/55/Chatsworth_maze.jpg/330px-Chatsworth_maze.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/55/Chatsworth_maze.jpg/440px-Chatsworth_maze.jpg 2x" data-file-width="2978" data-file-height="1867" /></a><figcaption>Chatsworth maze</figcaption></figure> <p><br /> </p><p>The assumption behind this theory is that the reader perceives the sentence as being set in only one context. There is a failure to perceive that there may be another context or way to interpret the sentence based on the noun phrases. The reader remains confident in their perceived judgement and assumes they are right. Garden path sentences create confusion as the reader's preconceived judgments are shattered (van Gompel et. al., 2006). <br /><br /> There are generally three alternative ways how a person could perceive a sentence:<br /> </p> <ol><li>Assemble a structure for just one of the possible interpretations and ignore all others (like the garden path model)</li> <li>Take into consideration all of the possible interpretations for the noun phrase at the same time</li> <li>Complete a partial analysis, with minimal commitment to one perception, waiting to make a final decision until more information is obtained. <br /> <br /></li></ol> <div class="mw-heading mw-heading3"><h3 id="Principles_that_Guide_the_Garden_Path_Model">Principles that Guide the Garden Path Model</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=13" title="Edit section: Principles that Guide the Garden Path Model" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=13" title="Edit section's source code: Principles that Guide the Garden Path Model"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are two principles of the Garden Path Model which explain how incorrect assignment of roles in a sentence can create confusion. <br /> </p> <div class="mw-heading mw-heading4"><h4 id="Late_Closure">Late Closure</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=14" title="Edit section: Late Closure" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=14" title="Edit section's source code: Late Closure"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>This parsing error is when the new words and phrases that are creating confusion to be attached to the already open phrase (a phrase that is already being processed).<br /> An example of this type of error is: The horse raced past the barn fell (can also be written as: The horse that raced past the barn fell). </p> <div class="mw-heading mw-heading4"><h4 id="Minimal_Attachment">Minimal Attachment</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=15" title="Edit section: Minimal Attachment" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=15" title="Edit section's source code: Minimal Attachment"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>This is when the reader uses the simplest strategy to help understand the sentence.

More research has to be completed to compare other language parsing to determine if one theory can simply encompass all languages (MacWhinney & Bates, 1993). </p> <div class="mw-heading mw-heading2"><h2 id="Computers_and_Parsing">Computers and Parsing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=22" title="Edit section: Computers and Parsing" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=22" title="Edit section's source code: Computers and Parsing"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Acer_Aspire_8920_Gemstone.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/7b/Acer_Aspire_8920_Gemstone.jpg/220px-Acer_Aspire_8920_Gemstone.jpg" decoding="async" width="220" height="159" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/7b/Acer_Aspire_8920_Gemstone.jpg/330px-Acer_Aspire_8920_Gemstone.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/7b/Acer_Aspire_8920_Gemstone.jpg/440px-Acer_Aspire_8920_Gemstone.jpg 2x" data-file-width="3130" data-file-height="2258" /></a><figcaption> Parsing by computers is difficult, but achievable.</figcaption></figure> <p>Although the vast majority of information presented has been regarding the natural English language, it must be noted that computers are now programmed to be able to correctly parse. First of all, lexicons are established, if the computer is parsing English, the lexicons would be the entire English dictionary. Grammar rules must then be established. When a computer encounters a sentence, it parses the sentence multiple times, creating tree diagrams until a viable meaning is found (Ashcraft, 2006). <br /> However, there is a problem with ambiguity when a computer parses sentences. Many sentences in the English language are vague and rely on either probability or context to determine the meaning of a sentence. Computers can do this, based on knowledge of previous conversations but more mistakes are made. <br /> <br /> A video describing parsing and computers can be found <a rel="nofollow" class="external text" href="https://www.youtube.com/watch?v=lOM31GXltyM">Here.</a> <br /> <br /> </p> <div class="mw-heading mw-heading2"><h2 id="Resources">Resources</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Psycholinguistics/Parsing&veaction=edit&section=23" title="Edit section: Resources" class="mw-editsection-visualeditor"><span>edit</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Psycholinguistics/Parsing&action=edit&section=23" title="Edit section's source code: Resources"><span>edit source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Ashcraft, M.H. & Klein, R.H.

List and describe the two principles of the garden path model. How do they differ? <br /> </p><p>2. You are parsing a sentence into a tree structure in Psycholinguistics class one day. Your friend beside you gets a different answer then you do. Is it possible that you are both right? <br /> a. How? <br /><br /> </p><p>3. What type of sentence processing most likely occurs when a sentence is being parsed? Why? <br /> <br /> </p><p>4. The steps in the Garden Path model is a metaphor for what language component? <br /><br /> </p><p>5. If a computer was parsing language, which of the four factors of Parsing do you think it would have the biggest problem with automating or doing as well as a human? Why? <br /><br /> </p>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://en.wikiversity.org/w/index.php?title=Psycholinguistics/Parsing&oldid=2170246">https://en.wikiversity.org/w/index.php?title=Psycholinguistics/Parsing&oldid=2170246</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Special:Categories" title="Special:Categories">Category</a>: <ul><li><a href="/wiki/Category:Psycholinguistics" title="Category:Psycholinguistics">Psycholinguistics</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 14 June 2020, at 02:09.</li> <li id="footer-info-copyright">Text is available under the <a rel="nofollow" class="external text" href="//creativecommons.org/licenses/by-sa/4.0/">Creative Commons Attribution-ShareAlike License</a>; additional terms may apply.
