monk lexicon work area for discussion Last updated 2007/10/04. LIST of TERMS in meaningful order
WORDS WE SHOULD AVOID USING if we are trying to be precise and avoid confusion:
------------------------- NOT UPDATED BELOW I DO NOT UPDATE THIS ALPHABETICAL LIST BECAUSE THIS IS NOT A GOOD WAY TO LEARN ABOUT THE VOCABULARY. AND IF YOU KNOW THE TERM YOU WILL JUST SEARCH FOR IT NOT SCROLL THE LIST (CP) ------------------------
ALPHABETIC LIST Adorned CollectionAn adorned colection is a collection in which the words in each work in the corpus have been adorned with morphological information such as part of speech and lemma. AdornmentAdornment is the process of adding information such as morphological information to texts. We use the term "adornment" in preference to terms such as "annotation" or "tagging" which carry too many alternative and confusing meanings. Adornment harkens back to the medieval sense of manuscript adornment or illumination performed by monks - attaching pictures and marginal comments to texts. AffixAn affix is a prefix or suffix which can be added to a morpheme or word to modify its meaning. Attribute (in machine learning terms only)An attribute in machine learning terms is a property of an object which may be used to determine its classification. For example, one attribute of a literary work is its genre: play, novel, short story, etc. Bayes's RuleBayes's rule defines the condssitional probability for two events A and B as follows: Pr(A | B) = Pr(B | A) * Pr(A) / Pr(B) BigramA bigram is an ordered sequence of two adjacent words, characters, or morphological adornments. Bound MorphemeA bound morpheme is a prefix or suffix which is not a word but which can be attached to a free morpheme to modify its meaning. For example, the bound morpheme "un" may be attached to the free morpheme "known" to form the new morpheme/word "unknown." PartA part (called chunk before) is a part of a work residing in a collection. A chunk consists of an ordered series of words and associated morphological information with a label. A chunk may be treated as a bag of words or ngrams for data analysis and navigation. CollocateWords which appear near each other in a text more frequently than we would expect by chance are called collocates. Collocates may be ngrams, but may also consist of multiple words with gaps between one or more of the words. ComponentA component is a bundle of services. A component knows how to render messages. CollectionA Collection is a set of works. Data HerdingData herding is the process of acquiring, combining, editing, normalizing, and warehousing texts so they can be used for further analysis. DatastoreA datastore means a query-able data source. Document Coordinate SystemA document coordinate system assign a numeric vector of coordinate values to the position of each token in a document. A typical coordinate value might consist of a pair of line and column values based upon the printed form of the text, or a character offset and length pair based upon the digitized text. Edit DistanceThe edit distance between two strings of characters is the number of operations required to transform one of them into the other. The most commonly use transformation operations are character insertion, character deletion, and character replacement. FeatureTO ADD Free MorphemeA free morpheme is the basic or root form of a word. Bound morphemes can be attached to modify the meaning. Hard tagA hard tag is an SGML, HTML, or XML tag which starts a new text segment but does not interrupt the reading sequence of a text. Examples of hard tags include <div> and <p>. Hidden Markov ModelA hidden Markov model (HMM) is a statistical model in which the system being modeled is assumed to be a Markov process with unknown parameters. The problem is to find the unknown parameters using values of the observable model parameters. HMMAbbreviation for hidden markov model. InterfaceInterface means user interface(s) Jump tagA jump tag is an SGML, HTML, or XML tag which interrupts the reading sequence of a text and starts a new text segment. Examples of jump tags include <note> and <speaker>. Keyword ExtractionKeyword extraction extracts "interesting" phrases which characterize a text. Language RecognitionLanguage recognition attempts to determine the language(s) in which a text is written. Literary texts are generally composed in one principal language with possible inclusions of short passages (letters, quotations) from other languages. It is helpful to categorize texts by principal language and most prominent secondary language, if any. We can use statistical methods based upon character ngrams and rank order statistics to determine the principal language of a text and list possible secondary languages. LemmaThe lemma form or lexical root of an inflected spelling is the base form or head word form you would find in a dictionary. A lemma can also refer to the set of lexemes with the same lexical root, the same major word class, and the same word-sense. LemmatizationLemmatization is the process of reducing an inflected spelling to its lexical root or lemma form. The lemma form is the base form or head word form you would find in a dictionary. LexemeA lexeme is the combination of the lemma form of a spelling along with its word class (noun, verb. etc.). LexiconA lexicon is a collection of words and their associated morphological information as used in a corpus. Machine LearningMachine learning occurs when a computer program modifies itself or "learns" so that subsequent executions with the same input result in a different and hopefully more accurate output. Machine learning methods may be supervised, i.e., using training data, or unsupervised, without using training data. Markov ProcessA Markov process is a discrete state random process in which the conditional probability distribution of the future states of the process depends only upon the present state and not on any past states. MessageA message is a query or the result of a query. ????????? Middleware (OR PROXY???)Middleware means the stuff between the interface and the datastore(s). MorphAdornMorphAdorn used as a verb is a Monk neologism which means "to adorn a text using MorphAdorner." MorphAdornerMorphAdorner is a suite of Java programs which performs morphological adornment of words in a text. A high-level description of MorphAdorner's capabilities appears at http://apps.lis.uiuc.edu/wiki/display/MONK/About+MorphAdorner. MorphemeA morpheme is a minimal grammatical unit of a language. A morpheme consists of a word or meaningful part of a word that cannot be divided into smaller independent grammatical units. Multiword UnitA multiword unit is a special type of collocate in which the component words comprise a meaningful phrase. ??????? Named EntityA named entity is a multiword unit consisting of a type of name such as a personal name, corporate name, place name, or date. NgramAn ngram is an ordered sequence of n adjacent words, characters, or morphological adornments. NUPOSNUPOS is a part of speech tag set devised by Martin Mueller to allow part of speech tagging of English texts from all periods as well as texts in classical languages. Further information about NUPOS appears in Morphology and NUPOS. Part of SpeechThe part of speech is the role a word performs in a sentence. A simple list of the parts of speech for English includes adjective, adverb, conjunction, noun, preposition, pronoun, and verb. For computational purposes, however, each of these major word classes is usually subdivided to reflect more granular syntactic and morphological structure. Part of Speech TaggingPart of speech tagging adorns or "tags" words in a text with each word's corresponding part of speech. Part of speech tagging relies both on the meaning of the word and its positional relationship with adjacent words. PhoneA phone is an acoustic pattern which apeakers of a particular natural language consider distinguishable and linguistically important. Distinct phones in one language may be grouped together and treated as the same sound in another language. PhonemeA phoneme is a group of phones considered to be the same sound by speakers of a specific natural language. One or more phonemes combine to form a morpheme. PrefixA prefix consists of characters comprising one or more bound morphemes which can be added to the front of a word to modify its meaning. Pronoun Coreference ResolutionPronoun coreference resolution matches pronouns with the nouns to which they refer. Some pronouns may not actually refer to a specific noun. For example, in the sentence "It is not clear how to proceed" the initial pronoun "It" does not refer to any specific noun. Pseudo-bigramA pseudo-bigram generalizes the computation of bigram statistical measures to ngrams longer than two words by splitting the original multiword units into two groups of words, each treated as a single "word". Sentence SplittingSentence splitting assembles a tokenized text into sentences. Recognizing sentence boundaries is a difficult task for a computer and generally requires a combination of rules and statistical methods. Sentiment Assignment ?????ServiceA service is a list of messages that serve a particular component. Soft tagA soft tag is an SGML, HTML, or XML tag which does not interrupt the reading sequence of a text and does not start a new text segment. Examples of soft tags include <hi> and <em>. SpellingThe spelling is the orthographic representation of a spoken word. Words may have more than one spelling, particularly in texts dating from earlier periods when spelling was not standardized. Spelling StandardizationSpelling standardization is the mapping of variant, often archaic, spellings to standard modern forms. StemmingStemming removes affixes from a spelling. The resulting stem is not necessarily a proper lexeme. Stemming offers a simpler alternative to lemmatization. Stemming can be useful in information retrieval applications, but is much less useful in literary applications. Popular stemmers include the Martin Porter's stemmer and the Lancaster (Paice-Husk) stemmer. String similarityString similarity is a measure of how similar two strings of characters are. A similarity of 0.0 indicates two strings are completely different, while a similarity of 1.0 indicates two strings are identical. Dozens of different string similarity measures SuffixA suffix consists of characters comprising one or more bound morphemes which can be added to the end of a word to modify its meaning. Supervised LearningSupervised learning is a machine learning technique which predicts the value of a given function for any valid input after having been presented with training examples (i.e. pairs of input and correct output). Tagged CollectionSee adorned collection. Text Encoding InitiativeThe Text Encoding Initiative (TEI) Guidelines "are an international and interdisciplinary standard that enables libraries, museums, publishers, and individual scholars to represent a variety of literary and linguistic texts for online research, teaching, and preservation." More information may be found at the official Text Encoding Initiative site TEIAbbreviation for Text Encoding Initiative. TEISimpleTEISimple is a literary DTD created by Martin Mueller to enable the use of a common XML DTD across all texts to be included in Monk. A fuller description may be found at TEISimple A useful May Have?. TrigramA trigram is an ordered sequence of three adjacent words, characters, or morphological adornments. Unsupervised LearningUnsupervised learning is a machine learning method which fits a model to observed data without benefit of training data. Viterbi AlgorithmThe Viterbi algorithm allows searching a space containing an apparently exponential number of points to be searched in polynomial time. The Viterbi algorithm is frequently used in hidden Markov model statistical part of speech tagging applications to reduce the time complexity of seaches for the best tags for a sequence of spellings in a sentence. WordA word is the basic unit of a language. Words are composed of morphemes. Word Sense DisambiguationWord sense disambiguation is the process of distinguishing different meanings of the same word in different textual contexts. For example, a "bank" can be both a financial institution or a geographic location next to a river. Word TokenizationWord tokenization splits a text into words, whitespace, and punctuation. WorkA work is a single text which is a member of a Collection. Each work consist of one or more text segments called parts. PartSee chunk. |
