Lexical Ambiguity

Linear time, dynamic API for lexical analysis and parser generation. Allows for a text-based specification of formal languages with the well-known regular-expressions approach, and using Parsing Expression Grammars as the underlying engine.

A Python interface to the Wordnet database of word meanings and lexical relationships. allows the user to type expressions such as N['dog'], hyponyms(N['dog'][0]), and closure(ADJ['red'], SYNONYM) to query the database for lexical relationships.

VisualWN is a Java Client which provide graphic presentation of lexical searching result based on WordNet database. The main purpose of client is to make learning English vocabulary fun and easy.

In 1975, Vincenty published a rapidly converging algorithm for computing the distance between points on an ellipsoidal earth. The algorithm is precise to within a few millimeters. Since then, his algorithm has since seen significant implementation in geodesy and engineering. After adjusting the...

Often in program logic, multiple different steps need to be taken that are independent of each other, but their total result is needed before the next step can be taken. In synchonous code, the usual approach is to do them sequentially. An asynchronous or event-based program could do this, but...

Nasal is a language that I wrote for use in a personal project. Ostensibly it was because I was frustrated with the dearth of small-but-complete embeddable scripting languages, but of course I really wrote it because it was fun. It is still young and incomplete in a few places, but is under...
