CHEMISTRY: Lightly Switched Gel

Lightly-Supervised Attribute Extraction

Web search engines can greatly benefit from knowledge about attributes of entities present in search queries. In this paper, we introduce lightly-supervised methods for extracting entity attributes from natural language text. Using these methods, we are able to extract large numbers of attributes of different entities at fairly high precision from a large natural language corpus. We compare our...

The Power of Non-Hydrolytic Sol-Gel Chemistry: A Review

This review is devoted to non-hydrolytic sol-gel chemistry. During the last 25 years, non-hydrolytic sol-gel (NHSG) techniques were found to be attractive and versatile methods for the preparation of oxide materials. Compared to conventional hydrolytic approaches, the NHSG route allows reaction control at the atomic scale resulting in homogeneous and well defined products. Due to these features...

Chemistry and Fundamentals of the Sol–Gel Process

Surface-localized release of nitric oxide via sol-gel chemistry.

The release of nitric oxide (NO) from polymers has proven to be highly effective at inhibiting platelet adhesion and thus enhancing the blood compatibility of medical implants. Micropatterning techniques were used to design surfaces that release NO while preserving the underlying substrate for other applications (e.g., sensors). Micropatterned NO-releasing substrates based on aminosilane-contai...

Lightly Supervised Quality Estimation

Evaluating the quality of output from language processing systems such as machine translation or speech recognition is an essential step in ensuring that they are sufficient for practical use. However, depending on the practical requirements, evaluation approaches can differ strongly. Often, reference-based evaluation measures (such as BLEU or WER) are appealing because they are cheap and allow...
