The work presented in this thesis discusses various formal language formalisms that extend classical formalisms like regular expressions and context-free grammars with additional abilities, most relating to order. This is done while focusing on the impact these extensions have on the efficiency of parsing the languages generated. That is, rather than taking a step up on the Chomsky hierarchy to...

The present study aims at the description and analysis of the phonological and lexical development of a child who is acquiring Farsi as his first language. The child's language production at the holophrastic stage of language development, mainly single words, is observed and recorded  longitudinally for nearly seven  months since he was 16 months old until he turned 23 months. An attempt is mad...

Fingerspelling is a critical component of many sign languages. This manual representation orthographic code one key way in which signers engage translanguaging, drawing from all their linguistic and semiotic resources to support communication. Translanguaging bimodal bilinguals unique because it involves languages different modalities, namely signed language like American Sign Language spoken E...

Interfaces to other languages such as C and Fortran have provided S users access to a vast collection of existing software. Adding general interfaces to other languages allows us to access the software developed for those languages. In addition to providing S users with easy and immediate access to the functionality in languages such as Java, Python and Perl, these interfaces also work in rever...

There are around 5.000 spoken languages of the world today, and they are all different. Thus, natural languages are very diverse. However, most linguists share the view that the languages of the world, and the way they are used in different communities, have a lot in common. The properties that all languages have in common are called language universals. Linguists have claimed of many different...

This paper describes research activities of ETRI in multi-lingual spontaneous speech translation. We have developed Korean-toEnglish, Korean-to-Japanese speech translation system prototype that includes 5,000 word spontaneous Korean speech recognizer, Korean-English and Korean-Japanese translators, and Korean speech synthesizer with spontaneous prosody in the travel planning task. We utilize mu...

Many complicated techniques have been introduced to aid in computer processing of natural languages. While this is generally considered to be a difficult task, many approaches have ignored the prevalent class of monolexical languages, or languages that consist of a single word. Here we present some desirable properties of such languages and apply techniques for common NLP tasks.
