Our activity over Internet is carefully monitored (links, keywords used in queries, the computers on which we connect the Internet, etc.)

Some of them have to making our life easier, and others can report anti-social or harmful to society (such task the Wikipedia Vandalism from CLEF2010)

It is up to the invocation of national security (after 11 September) and to the interests of big companies

There are resources available from Yahoo (Cries task from Clef 2010) or from Wikipedia

Yahoo!Questions and Answers (Surdeanu M., M. Ciaramita, H. Zaragoza, ACL 2008) aim is to identify human experts in a field

We want to find out users’ opinions on various products or events◦ I want to buy a certain product (eg iPhone). What

are the strengths and weaknesses of it are? What say persons who have used it already?

Google API, Yahoo API

Social Networks (MySpace, Facebook, Twitter)

We initially had performance issues (because we prefer Wikipedia pages)

Solution: we added additional criteria to prefer blogs, forums, or areas that allow to add personal comments and opinions

Romanian researchers working on English, Spanish, the Romanian (Dan Tufiş, Rada Mihalcea, Alexandra Balahur)

Other researchers (Carlo Strapparava, A. Montoyo)

Used techniques involve disambiguation, the use of SentiWordNet resources, identify triggers feelings, etc.LiSS Conference, 3-5 May, Iasi

Based on the resources from English language (A. Balahur and A. Montoyo, 2008) we build our resources specific to the Romanian language

Using the Romanian WordNet (Tufiş et al., 2004) we extended this resource

The resources we have completed and adapted (Iftene, Rotaru, 2010) with specific terms used in social networks or in blogs

Specific terms: “successfully”, “super”, “fine”, “good” and emotional icons ":)" (smiley face ), “” (sad face ), etc.

We considered a set of principal terms representing positive triggers (pride, family, home, freedom, esteem, etc..), and another set of principal terms representing negative triggers (murder, treason, cowardice, etc.).

Synonyms and hyponyms of principal terms were added to the same set to which they belonged

Antonyms of principal terms were added to other sets

Terms that changes valence to another term that accompany

Negations - which (radically) change valence (“no”, “never”)

Amplifiers - that emphasize the positive or negative aspect of a trigger (adjectives: “high”, “more”, “better”, “profound”, “exceptional”, adverbs: “definitely”, “sure”, “certainly”, “ultimately”)

Diminished - that diminishes the positive or negative or positive valence of a trigger, going to a neutral valence (adjective “small”, “less”, “worse”, “rather” modal verbs “can”, “possible”, “must”, “want” adverbs: “probably”)

1. Alex is a good person.“good” is a positive trigger

2. Ben is a very good person.“good” as positive trigger, but we have also the

amplifier “very”

3. John is the best.“best” is a positive trigger with the strongest

intensity LiSS Conference, 3-5 May, Iasi

Page 15: I See You, You Can't See Me: On People's Perception About Surveillance In Post Totalitarian Romania

A1. Alex is a good person. A2. Ben is not a good person.

we have the antonym relation: good ≠ not good (= bad)

B1. John is the best. B2. Thomas is not the best.

we consider not the best to be somewhere between good and the best

We are interested to see what are Romanian people opinions regarding listening and interception of their communications

We generate queries in Romanian using basic words: ◦ SMS, e-mail, mobile/fixed phone, e-mail,

chat and additional words representing Romanian

organizations:◦ SRI - Romanian Intelligence Service◦ DNA - National Anticorruption

LiSS Conference, 3-5 May, Iasi

Page 17: I See You, You Can't See Me: On People's Perception About Surveillance In Post Totalitarian Romania

In total we obtained over 30 queries and around 100 links corresponding to searches with these queries (after filtering phase)

LiSS Conference, 3-5 May, Iasi

Positive opinions (10%)

Negative opinions (30%)

Neutral opinions (60%)

Page 18: I See You, You Can't See Me: On People's Perception About Surveillance In Post Totalitarian Romania

Positive opinions: ◦ it can intercept corrupt politicians, ◦ businessmen who have illegal business,◦ terrorist acts in time

Negative opinions: ◦ we have the right to privacy◦ interceptions are used for extortion and intimidation,

or to eliminate business competition Neutral opinions:◦ users who say they have nothing to hide, nor did that

they would interest in what other persons doing◦ In many cases users come with ironic comments

regarding to SRI capabilities to surprise even any communication

“Law no. 298/2008 related to retention of data generated or processed by providers of electronic communications ... ” issued on 18 November 2008 by the Romanian Parliament

Negative opinions: ◦ In many cases, users see the law a return back in

communist times when security was using wiretaps for the oppression of the population◦ The other comments are critical of the

television and newspapers that have shown the introduction of this law

“Law no. 298/2008 related to retention of data generated or processed by providers of electronic communications ... ” issued on 18 November 2008 by the Romanian Parliament

Positive opinions: ◦ One of them is a technical comment that explain

how data transfer protocols that track network packets route across a network, may report errors and can correct them if they know who and to whom was sent the package◦ Other messages show that this law will be beneficial

for tracking crime groups

On six subjects, three people were evaluated over 100 paragraphs => ~ 44% classification accuracy

For Romanian, there are major differences between the number of search results obtained using Google or Yahoo and search on social networks

On English language searches have enough results by both methodsLiSS Conference, 3-5 May, Iasi

Page 23: I See You, You Can't See Me: On People's Perception About Surveillance In Post Totalitarian Romania

Existing information on the Internet are very useful

Case study on wiretaps and monitoring activities on the Internet (chat, email, etc.) showed that are more negative opinions than positive ones

We could also find that negative views are focused on law adopted and the SRILiSS Conference, 3-5 May, Iasi
