CONTEXT-AWARE COMPUTING APPARATUS AND METHOD OF DETERMINING TOPIC WORD IN DOCUMENT USING THE SAME

摘要

Provided are a context-aware computing apparatus and a method of determining a topic word in a document using the same. The context-aware computing apparatus includes a memory configured to store information including a word graph in which semantic relationships among words are recorded in a network form, and a processor connected to the memory. The processor extracts content words from an acquired document by analyzing the document, clusters, in the word graph, word associations lying within a certain semantic distance from the position of each content word in the word graph, determines a centroid vector, which is a semantic center, for the content words and the word associations, determines topic words in order of increasing semantic distance from the determined centroid vector among the content words and the word associations, and provides the determined topic words.
