    JSON Iterator Java

    JSON Iterator Java

    jsoniter (json-iterator) is fast and flexible JSON parser

    jsoniter (json-iterator) is fast and flexible JSON parser available in Java and Go. A good deal of the code is ported from dsljson, and JSON parser. Traditional JSON parsers are slow. Jsoniter Java version could be 3x times faster than jackson/gson/fastjson. If you are doing a lot of log processing or number crunching, but stuck with JSON, you definitely need to consider dsl-json or Jsoniter to save the encoding/decoding cost. Is protobuf 5x faster than JSON?. Jsoniter Golang version could be more than 6x times faster than standard lib (encoding/json). And the number is acheived with runtime reflection instead of go generate.

    This project aims to provide a wrapper around the SentiWrodnet, a lexical resource for opinion mining.

You can find additional information about the creation of SentiWordnet here : http://nmis.isti.cnr.it/sebastiani/Publications/LREC06.pdf sentiWordnet (avilable here : https://drive.google.com/open?id=0B0ChLbwT19XcOVZFdm5wNXA5ODg) is a text file with a specific format that saves a synset on each line. In this project, we aim to provide a wrapper that allows developers to use SentiWordnet without the need to interact directly with the text file. The project allows simple interrogation using a simple GUI and a REST Web service.
