Cognitive approaches to L3 acquisition

Bilingualism and L3 Acquisition

مقاله حاضر کنش زبانی دوزبانه‌های آذری‌زبان و تک‌زبانه‌های فارسی‌ زبان را در فرایند یادگیری زبان سوم مورد بررسی قرار می‌دهد. پژوهش‌های موجود درباره توانایی‌های فرازبانی و شناختی زبان‌آموزان‌ کودک حاکی از این است که دوزبانه‌ها با توجه به کسب تجارب قبلی در یادگیری زبان دوم،در فراگیری زبان سوم موفق‌تر بوده و کنش زبانی آنها متفاوت‌تر از تک‌زبانه‌ها خواهد بود. در این تحقیق کنش زبانی دو گروه ده نفری ا...

New Approaches to Constraint Acquisition

In this chapter we present the recent results on constraint acquisition obtained by the Coconut team and their collaborators. In a first part we show how to learn constraint networks by asking the user partial queries. That is, we ask the user to classify assignments to subsets of the variables as positive or negative. We provide an algorithm, called QUACQ, that, given a negative example, finds...

Some Approaches to Knowledge Acquisition

Knowledge acquisition is not a single, monolithic problem for AI. There are many ways to approach the topic in order to understand issues and design useful tools for constructing knowledge-based systems. Several of those approaches are being explored in the Knowledge Systems Laboratory (KSL) at Stanford. BACKGROUND In 1969, while working on DENDRAL, we recognized the “bottleneck” problem of acq...

Stochastic Approaches to Morphology Acquisition

One of the first steps in acquiring a morphology system is discovering which phonetic strings correspond to morphemes. These phonetic strings can then be further analyzed in order to determine their grammatical privileges and contribution to meaning and thus to bootstrap into a functional morphology system. Discovering the relevant phonetic strings is a deceptively easy task. Morpheme discovery...
