Keyword extraction for metadata annotation of Learning Objects
نویسندگان
چکیده
One of the functionalities developed within the LT4eL project is the possibility to annotate learning objects semi-automatically with keywords that describe them. To this end, a keyword extractor has been created which can deal with documents in 8 languages. The approach employed is based on a linguistic processing step which is followed by a filtering step of candidate keywords and their subsequent ranking based on frequency criteria. Two tests have been carried out to provide a rough evaluation of the performance of the tool and to measure inter annotator agreement in order to determine the complexity of the task and to evaluate its performance with respect to human annotators.

Automatic Keyword Extraction for Learning Object Repositories
Introduction Learning object repositories are digital collections of educational materials, e.g., lectures, notes, presentations, which can be used to support learning. The main purpose of such repositories is to improve the sharing and reusability of the learning objects, which can be defined as “any digital resource that can be reused to support learning” (Wiley, 2000, p. 7). An important asp...

With the currently growing interest in the Semantic Web and Social Networking, personal metadata is coming to play an important role in the Web. This paper proposes a novel keyword extraction method to extract personal metadata from the Web. The proposed method is based on co-occurrence information of words. Our method extracts relevant keywords depending on the context of a person. Our experim...
متن کاملTaiWanese LOM (TW LOM) Annotation: Automatic Description Generation for Learning Objects
Owning to the great growth of e-learning objects, authorities (e.g. ADL and IEEE) have developed some metadata standards to facilitate the keyword search for various e-learning applications. However, too much fields, such as 58 blank fields in IEEE LOM, waiting for authors or annotators to fill up become an endless nightmare. In order to reach our vision of sharing and reusing valuable assets, ...
متن کاملSemantic annotation of multilingual learning objects based on a domain ontology
One of the important tasks in the use of learning resources in e-learning is the necessity to annotate learning objects with appropriate metadata. However, annotating resources by hand is time consuming and di cult. Here we explore the problem of automatic extraction of metadata for description of learning resources. First, theoretical constraints for gathering certain types of metadata importa...
متن کاملAutomatic Extraction of Pedagogic Metadata from Learning Content
Annotating learning material with metadata allows easy reusability by different learning/tutoring systems. Several metadata standards have been developed to represent learning objects and courses. A learning system needs to use pedagogic attributes including document type, topic, coverage of concepts, and for each concept the significance and the role. Moreover, in order to have a flexible and ...
