Introduction

The various advances in IT have created the need for systems dependent on context. The purpose of these systems is to provide information which depend on the user's environment to improve its interaction with different systems they use every day.

social networks in the internet are web services that allow individuals to build a linked public or semi-public profile with a list of other profiles that requires bi-directional confirmation for the hacker, but some networks do not, these Unidirectional links are sometimes labeled as fans or subscribers, with these friends he has relationships and he shares with them information.

The notion of context was used in linguistics and psychology before being adopted in computing, but also has a distant origin and a long history in philosophy. Mobility has given an important dimension to the context that touched many areas of IT application as computer ubiquitous artificial intelligence, processing of natural language (cognitive computing), ... etc.

We can define the context as any information that can be used to characterize the situation of an entity. An entity is a place, person, or object that is considered relevant to the interaction between a user with social media. The context may include the location, the person's identity, the people around person, activities or products of interest.

In this chapter we first define the notion of context of a person, and then do a study on the sentiments analysis in micro-blogs by detailing different techniques existed in literature.

Social Network Analysis

Social network analysis is a process of quantitative and qualitative analysis of a social network. it measures and maps the flow of relationships and changes in the relationships between entities with knowledge. these simple and complex entities of the websites can be people, groups, organizations and nations. We can see different methods in the literature that help to understand the relationships that people establish between themselves through the study of the intensity of their interactions, both in the world of work and in their private social community.

The analysis of sentiment (or tonality), also called opinion mining, is a concept that is often mentioned but often misunderstood. It is the process of determining the emotional tone behind a series of words. This analysis is used to better understand the perception, opinions and emotions expressed in an online statement. The purpose of this section is to understand the sentiment analysis: what is it and what is it for?

The Uses of Sentiment Analysis

Sentiment analysis is extremely useful in social media it provides an overview of public opinion about certain topics. The standby tools make this process faster and easier than ever thanks to their real-time scanning capabilities. The uses of sentiment analysis are both vast and powerful. The ability to extract insights from social web data is a practice that is widely adopted by companies around the world. It has been shown that tone changes on social media correlate with changes in the stock market. For example, the Barack Obama administration used sentiment analysis to measure public opinion against various reforms and campaigns in preparation for the 2012 presidential elections. Being able to quickly understand and react to consumer attitudes has also been extremely helpful to Expedia's Canadian team, who has seen a surge in negative reviews of music used in one of their TV commercials.

The analysis of the feeling then led by the group revealed that the music used in their advertising became annoying after several broadcasts. Consumers turned to social media to express their dissatisfaction. A few weeks after the first broadcast, more than half of the social web discussions about the campaign were negative. Rather than resigning to failure, Expedia was able to respond in an informed and entertaining manner by releasing a new version of the ad that showed the culprit, a violin, being destroyed.

Contextual Understanding And Tone

But the analysis of feeling remains an inexact science because the Human language is complex. Teaching a machine how to analyze grammatical and / or cultural nuances, slang and spelling mistakes that are common things online is a difficult process. Teaching a machine how the context can influence the tone is even more difficult.
