Noisy text analytics: Noisy text analytics is a process of information extraction whose goal is to automatically extract structured or semistructured information from noisy unstructured text data.  While Text analytics is a growing and mature field that has great value because of the huge amounts of data being produced, processing of noisy text is gaining in importance because a lot of common applications produce noisy text data.  Noisy unstructured text data is found in informal settings such as online chat, text messages, e-mails, message boards, newsgroups, blogs, wikis and web pages.  Also, text produced by processing spontaneous speech using automatic speech recognition and printed or handwritten text using optical character recognition contains processing noise.  Text produced under such circumstances is typically highly noisy containing spelling errors, abbreviations, non-standard words, false starts, repetitions, missing punctuations, missing letter case information, pause filling words such as “um” and “uh” and other texting and speech disfluencies.  Such text can be seen in large amounts in contact centers, chat rooms, optical character recognition (OCR) of text documents, short message service (SMS) text, etc.  Documents with historical language can also be considered noisy with respect to today’s knowledge about the language.  Such text contains important historical, religious, ancient medical knowledge that is useful.  The nature of the noisy text produced in all these contexts warrants moving beyond traditional text analysis techniques.

Language and gender: Research into the many possible relationships, intersections and tensions between language and gender is diverse.  It crosses disciplinary boundaries, and, as a bare minimum, could be said to encompass work notionally housed within applied linguistics, linguistic anthropology, conversation analysis, cultural studies, feminist media studies, feminist psychology, gender studies, interactional sociolinguistics, linguistics, mediated stylistics, sociolinguistics and media studies.  In methodological terms, there is no single approach that could be said to 'hold the ﬁeld'.  Discursive, poststructural, ethnomethodological, ethnographic, phenomenological, positivist and experimental approaches can all be seen in action during the study of language and gender, producing and reproducing what Susan Speer has described as 'different, and often competing, theoretical and political assumptions about the way discourse, ideology and gender identity should be conceived and understood'.  As a result, research in this area can perhaps most usefully be divided into three main areas of study: first, there is a broad and sustained interest in the varieties of speech associated with a particular gender; second, there is a related interested in the social norms and conventions that (re)produce gendered language use (a variety of speech (or sociolect) associated with a particular gender is sometimes called a genderlect); and third, there are studies that focus on the contextually specific and locally situated ways in which gender is constructed and operationalized.  The study of gender and language in sociolinguistics and gender studies is often said to have begun with Robin Lakoff's 1975 book, "Language and Woman's Place", as well as some earlier studies by Lakoff.  The study of language and gender has developed greatly since the 1970s.  Prominent scholars include Deborah Tannen, Penelope Eckert, Janet Holmes, Mary Bucholtz, Kira Hall, Deborah Cameron, and others.  The 1995 edited volume "Gender Articulated: Language and the Socially Constructed Self" is often referred to as a central text on language and gender.

Yiddish: Yiddish (ייִדיש , יידיש or אידיש , "yidish"/"idish", "Jewish", ] ] ; in older sources ייִדיש-טײַטש "Yidish-Taitsh", Judaeo-German) is the historical language of the Ashkenazi Jews.  It originated during the 9th century in Central Europe, providing the nascent Ashkenazi community with a High German-based vernacular fused with elements taken from Hebrew and Aramaic as well as from Slavic languages and traces of Romance languages.  Yiddish is written with a fully vocalized alphabet based on the Hebrew alphabet.

List of Egyptologists: This is a partial list of Egyptologists.  An Egyptologist is any archaeologist, historian, linguist, or art historian who specializes in Egyptology, the scientific study of Ancient Egypt and its antiquities.  Demotists are Egyptologists who specialize in the study of the Demotic language and field of Demotic Studies.  Although a practitioner of the disciplined study of Ancient Egypt and Egyptian antiquities is an "Egyptologist", the field of Egyptology is not exclusive to such practitioners.

Philology: Philology is the study of language in written historical sources; it is a combination of literary criticism, history, and linguistics.  It is more commonly defined as the study of literary texts and written records, the establishment of their authenticity and their original form, and the determination of their meaning.  A person who pursues this kind of study is known as a philologist.

Universal language: Universal language may refer to a hypothetical or historical language spoken and understood by all or most of the world's population.  In some contexts, it refers to a means of communication said to be understood by all living things, beings, and objects alike.  It may be the idea of an international auxiliary language for communication between groups speaking different primary languages.  In other conceptions, it may be the primary language of all speakers, or the only existing language.  Some religious and mythological traditions state that there was once a single universal language among all people, or shared by humans and supernatural beings.

Cajun English: Cajun English, or Cajun Vernacular English, is the dialect of English spoken by Cajuns living in southern Louisiana and, to some extent, in eastern Texas.  Cajun English is significantly influenced by Cajun French, the historical language of the Cajun people, who descended from Acadian settlers and others.  It is derived from Acadian French and is on the List of dialects of the English language for North America.  This differed markedly from Metropolitan or Parisian French in terms of pronunciation and vocabulary, particularly because of the long isolation of Acadians, and even more so of Cajuns, from the Francophone world.

Sociology of language: Sociology of language is the study of the relations between language and society.  It is closely related to the field of sociolinguistics, which focuses on the effect of society on language.  One of its longest and most prolific proponents was Joshua Fishman, who among other major contributions, was founding editor of the "International Journal of the Sociology of Language".  Sociology of language studies society in relation to language whereas Sociolinguistics studies language in relation to society.  For the former, society is the object of study, whereas, for the latter, language is the object of study.  The basic idea is that language reflects, among several other things, attitudes that speakers want to exchange or that just get reflected through language use.  These attitudes of the speakers is the sociologist's information.
