This chapter presents an adaptation of existing techniques in Arabic morphology by leveraging corpus statistics to make them suitable for Information Retrieval (IR). The adaptation resulted in the development of Sebawai, an shallow Arabic morphological analyzer, and Al-Stem, an Arabic light stemmer. Both were used to produce Arabic index terms for Arabic experimentation. Sebawai is concerned wi...

It is challenging to translate names and technical terms from English into Arabic. Translation is usually done phonetically: different alphabets and sound inventories force various compromises. For example, Peter Streams may come out as hr..~ ~ bytr szrymz. This process is called transliteration. We address here the reverse problem: given a foreign name or loanword in Arabic text, we want to re...

This paper surveys some of the literature pertaining to searching and retrieving OCR’ed printed documents with emphasis on Arabic documents. It examines peculiarities of Arabic morphology, orthography, retrieval, word clustering, display, OCR, and error correction. The paper surveys existing evaluation test-beds for retrieval of Arabic OCR texts. Lastly, it concludes with possible directions fo...

Reformulating the user query is a technique that aims to improve the performance of an Information Retrieval System (IRS) in terms of precision and recall. This paper tries to evaluate the technique of query reformulation guided by an external resource for Arabic texts. To do this, various precision and recall measures were conducted and two corpora with different external resources like Arabic...

The performances of general and Arabic search engines were compared based on their ability to retrieve morphologically related Arabic terms. The findings highlight the importance of making users aware of what they miss by using the general engines, underscoring the need to modify these engines to better handle Arabic queries.

This paper investigates the influence of both gender and culture on color preference. Inspection of previous studies of color preference reveals that many of these studies have poor control over the colors that are shown-the chromatic co-ordinates of colors are either not noted or the illuminant that colors are shown under is not controlled. This means that conclusions about color preference ar...

This paper presents the work toward developing a new comprehensive database for Arabic off-line handwriting recognition. The database includes: isolated Indian digits, numerical strings, Arabic isolated letters, and a collection of 70 Arabic words. Also, the database includes a free format sample of an Arabic date. A data entry form was designed to collect written samples from Arabic native spe...

In Cross-Language Information Retrieval (CLIR), queries in one language retrieve relevant documents in other languages. Machine-Readable Dictionaries (MRD) and Machine Translation (MT) systems are important resources for query translation in CLIR. We investigate the use of MT systems and MRD to Arabic-English and English-Arabic CLIR. The translation ambiguity associated with these resources is ...

Sentiment Analysis in the Arabic Language Using Machine Learning Sentiment analysis has recently become one of the growing areas of research related to natural language processing and machine learning. Much opinion and sentiment about specific topics are available online, which allows several parties such as customers, companies and even governments, to explore these opinions. The first task is...
