In English, for instance, a noun can be in singular and plural number and each can take a genitive ending: base form genitive singular lentil lentil’s plural lentils lentils’ which is not too complex. In Swedish a noun can take number, definiteness, and genitive, yielding eight surface forms for most nouns: base form genitive non definite definite non definite definite singular sill sillen sills sillens plural sillar sillarna sillars sillarnas which…

In the game of buzzword bingo, players tick off pre-defined buzzwords available on a bingo-like board. But what to enter as buzzwords? How would you recognize such a word? In my view, many of the business terms I’ve encountered would qualify as…

Getting started with Gavagai Explorer

Quick video version on Youtube. Gavagai Explorer is a tool to analyze related texts to find common topics, their associated terms, their sentiment scores and their importance (in terms of number of respondent mentions). Although the primary use case for Explorer is open-ended question analysis of surveys it can be used for the analysis of any set of related texts such as hotel reviews. Gavagai Explorer aims to give the analyst a comprehensive and quantified view of the data; it identifies the main topics or topics and measures their importance as a relative strength to the total number of texts. This means that…
