Tweet recommendation under user interest modeling with named entity recognition

Karatay, Deniz
Twitter has become one of the most important communication channels with its ability of providing the most up-to-date and newsworthy information. Considering wide use of Twitter as the source of information, reaching an interesting tweet for a user among a bunch of tweets is challenging. As a result of huge amount of tweets sent per day by hundred millions of users, information overload is inevitable. In order for users to reach the information that they are interested easily, recommendation of tweets is an essential task. To extract information from this large volume of tweets, Named Entity Recognition (NER), is already being used by researchers. Commonly used NER methods on formal texts such as newspaper articles are built upon on linguistic features extracted locally. However, considering the short and noisy nature of tweets, performance of these methods is inadequate on tweets and new approaches have to be generated to deal with this type of data. Recently, tweet representation based on segments in order to extract named entities has proven its validity in NER field. Along with named entities extracted from tweets via tweet segmentation, user’s retweet and mention history, and followed users are also considered as strong indicators of interest and a model representing user interest is generated. Reducing Twitter users’ effort to access tweets carrying the information of interest is the main goal of the study, and a tweet recommendation approach under a user interest model generated via named entities is presented.

In the world of information, internet becomes the most important information source. However, internet contains vast amount of information and this information is not filtered. In such an environment, the people who seek for an information is overwhelmed in the alternatives that s/he can reach via the web. Recommender systems have their real importance in this kind of situations. To overcome said overwhelming problems, recommender systems are developed to determine the people needs and to recommend suitable...

Since accessing the Internet is getting easier and people are more willing to share information on the Internet than the previous generations, the data on such kind of reachable sources are growing very rapidly day by day. Moreover, because of the popularity and widely usage of those sources, the information which researchers and organizations are interested in can be found somewhere in these data collection. The purpose of Information Extraction (IE) is to analyze this information cloud and to extract the ...

Twitter is a very popular microblogging platform that has been actively used by scientific communities to exchange scientific information and to promote scholarly discussions. The present study aimed to leverage the tweet data to provide valuable insights into the development of the learning analytics field since its initial days. Descriptive analysis, geocoding analysis, and topic modeling were performed on over 1.6 million tweets related to learning analytics posted between 2010-2021. The descriptive anal...
Using google analytics and think-aloud study for improving the information architecture of METU Informatics Institute website: a case study
Demirel Kütükçü, Seher; Taşkaya Temizel, Tuğba; Department of Information Systems (2010)
Today, web sites are important communication channels that reach a wide group of people. Measuring the effectiveness of these web-sites has become a key issue for researchers as well as practitioners. However, there is no consensus on how to define web site effectiveness and which dimensions need to be used for the evaluation of these web sites. This problem is more noteworthy for information driven web sites like academic web sites. There is limited academic literature in this predominant application area....
Combining topology-based & content-based analysis for followee recommendation on Twitter
Yanar, Aysu; Karagöz, Pınar; Taşkaya Temizel, Tuğba; Department of Information Systems (2015)
Twitter has become an important social platform for individuals and people share a high number of information about their personal lives, interests and viral news during emergencies. As of 2014, Twitter has 240 million active users and approximately 500 million tweets are shared every day. This information overload in Twitter has become a serious problem due to the growing volume of messages and increasing number of users. Recommender systems help to overcome this challenge. Finding interesting users and ge...
