  • We propose a novel method to automatically acquire a term-frequency-based taxonomy from a corpus using an unsupervised method. A term-frequency-based taxonomy is useful for application domains where the frequency with which terms occur on their own and in combination with other terms imposes a natural term hierarchy. We highlight an application for our approach and demonstrate its effectiveness and robustness in extracting knowledge from real-world data.

  • This paper presents a novel metric-based framework for the task of automatic taxonomy induction. The framework incrementally clusters terms based on ontology metric, a score indicating semantic distance; and transforms the task into a multi-criteria optimization based on minimization of taxonomy structures and modeling of term abstractness. It combines the strengths of both lexico-syntactic patterns and clustering through incorporating heterogeneous features. The flexible design of the framework allows a further study on which features are the best for the task under various conditions. ...

  • Concept taxonomies offer a powerful means for organizing knowledge, but this organization must allow for many overlapping and fine-grained perspectives if a general-purpose taxonomy is to reflect concepts as they are actually employed and reasoned about in everyday usage. We present here a means of bootstrapping finely-discriminating taxonomies from a variety of different starting points, or seeds, that are acquired from three different sources: WordNet, ConceptNet and the web at large.

  • The automatic interpretation of noun-noun compounds is an important subproblem within many natural language processing applications and is an area of increasing interest. The problem is difficult, with disagreement regarding the number and nature of the relations, low inter-annotator agreement, and limited annotated data. In this paper, we present a novel taxonomy of relations that integrates previous relations, the largest publicly-available annotated dataset, and a supervised classification method for automatic noun compound interpretation.

  • We propose a novel algorithm for inducing semantic taxonomies. Previous algorithms for taxonomy induction have typically focused on independent classifiers for discovering new single relationships based on hand-constructed or automatically discovered textual patterns. By contrast, our algorithm flexibly incorporates evidence from multiple classifiers over heterogenous relationships to optimize the entire structure of the taxonomy, using knowledge of a word’s coordinate terms to help in determining its hypernyms, and vice versa. ...

  • Phân lớp văn bản là quá trình gán văn bản một cách tự động vào một hoặc nhiều lớp cho trước. Tuy nhiên, trong trường hợp có số lượng khá lớn các lớp, bài toán sẽ phức tạp hơn rất nhiều, do đó, khi tiến hành phân lớp thường cho kết quả có độ chính xác không cao. Vì vậy, một vấn đề được đặt ra là cần phân lớp các văn bản sử dụng cấu trúc phân cấp. Hiện nay, bài toán này đã và đang trở thành lĩnh vực nhận được nhiều sự quan tâm, nghiên cứu...

  • Our aim is to use conventional MRDs, with no explicit semantic coding, to obtain a comparable accuracy. The system we propose is capable of 1) performing fully automatic extraction (with a counterpart in terms of both recall and precision fall) of taxonomic links of dictionary senses and 2) ranking the extracted relations in a w a y that selective manual refinement is allowed.

  • Semantically clean inheritance of structured descriptions, taxonomic classification of gpneric knowledge, intensional structures for functional roles (including the possibility of multiple fillers), and procedural attachment (with automatic invocation) make it particularly useful in computer-based natural language understanding. We have implemented a prototype natural language system that uses KLONE extensively in several facets of its operation.

  • Bản chất phương pháp phân loại đất theo FAOUNESCO? Giống như phương pháp phân loại đất Soil Taxonomy, các tác giả của hệ thống phân loại FAO- UNESCO cũng dựa vào tính chất hiện tại của đất có liên quan tới nguồn gốc, điều kiện và quá trình hình thành để tiến hành phân loại. Như vậy có thể cho rằng phương pháp của FAOUNESCO cũng là phương pháp định lượng (định lượng tầng chẩn đoán và tính chất chẩn đoán).
