The computing cost of many NLP tasks increases faster than linearly with the length of the representation of a sentence. For parsing the representation is tokens, while for operations on syntax and semantics it will be more complex. In this paper we propose a new task of sentence chunking: splitting sentence representations into coherent substructures. Its aim is to make further processing of long sentences more tractable. We investigate this idea experimentally using the Dependency Minimal Recursion Semantics (DMRS) representation.

Background: The aim of this research is to evaluate analgesic effectiveness of infrared radiation and interference currents in degenerative diseases of joints. On the grounds of current practical and theoretical experience, the following hypothesis was formed: Application of interference currents and infrared radiation constitutes effective analgesic therapy in degenerative diseases, and in the case of the applied treatment, its effectiveness is long-term.Material/Methods: Tests were conducted on a group consisting of 32 women and men in the age range of 65-87 years of age suffering from a degenerative disease of the knee joint. The patients were applied a series of 10 treatments with application of the Sollux lamp for 15 minutes and interference currents of 50-100 HZ frequency for 5 minutes and 90- 100 Hz for 10 minutes during treatment. Evaluation of the efficiency of therapy was checked by means of the VAS scale and the Laitinen scale.Results: The results indicate an efficient analgesic effect according to the VAS scale immediately after treatment p = 0.002 and a month after treatment p = 0.000 as well as according to the Laitinen scale immediately after treatment p = 0.004 and a month after treatment p = 0.004.Conclusions: Application of infrared radiation and interference currents indicates an analgesic effect. These treatments may be alternative or supportive to pharmacological treatment in the case of degenerative changes in people who are over 65 years of age. Results of the research suggest continuation of further research on the effectiveness of the above-mentioned therapy and the length of preserving analgesic results in people with degenerative diseases of joints

We propose sentence chunking as a way to reduce the time and memory costs of realization of long sentences. During chunking we divide the semantic representation of a sentence into smaller components which can be processed and recombined without loss of information. Our meaning representation of choice is Dependency Minimal Recursion Semantics (DMRS). We show that realizing chunks of a sentence and combining the results of such realizations increases the coverage for long sentences, significantly reduces the resources required and does not affect the quality of the realization.
