Semantic change happens both in the long term (over years and decades) and in the very short term (in a single dialogue)1. An exploratory study of a Map Task dialogue indicates that dialogue participants coordinate on an ad-hoc vocabulary and associated concepts (meanings) to enable information exchange, and that adhoc vocabularies can be cobbled together from a heterogeneous mix of “microvocab...

Most programming languages have certain phrases (like expressions) which only read information from the state and certain others (like commands) which write information to the state. These are called passive and active phrases respectively. Semantic models which make these distinctions have been hard to find. For instance, most semantic models have expression denotations that (temporarily) chan...

Mining natural language text for real world applications can benefit from a data representation that encodes semantic structure. Tree-based features, however, limit the available learning methods. This paper presents a study where semantic frames are used to mine financial news so as to quantify the impact of news on the stock market. We represent news documents in a novel semantic tree structu...

semantic shifting which is one of the most important semantic processes forming the meaning of some linguistic structures was first introduced by safavi (1379). the meaning of different structures such as proverbs, are made by semantic shifting which takes place on the syntagmatic axis, but is shown on the paradigmatic axis. the corpus used in this study consists of 10 persian proverbs which ar...

Knowledge domains and their semantic representations via ontologies are typically subject to change in practical applications. Additionally, engineering of ontologies often takes place in distributed settings where multiple independent users interact. Therefore, change management for ontologies becomes a crucial aspect for any kind of ontology management environment. We introduce a new RDF-cent...

Psychological analysis of language has repeatedly shown that an individual’s rate of mentioning 1st person singular pronouns predicts a wealth of important demographic and psychological factors. However, these analyses are performed out of context — syntactic and semantic — which may change the magnitude or even direction of such relationships. In this paper, we put “pronouns in their context”,...
