Whare are the current limitations of cross lingual information retrieval systems?5 answersCurrent limitations of cross-lingual information retrieval systems include performance gaps between high and low-resource languages due to unbalanced pre-training data, the challenge of learning phrase representations for cross-lingual phrase retrieval, and the scarcity of cross-lingual training data in emergent domains. Additionally, the lack of cross-lingual retrieval data for low-resource languages makes training cross-lingual retrieval models more challenging. Furthermore, existing methods often focus on word or sentence-level representations, neglecting the need for effective phrase representations in cross-lingual retrieval tasks. These limitations hinder the optimal performance and generalizability of cross-lingual information retrieval systems, especially in scenarios involving low-resource languages and emerging domains.
Why are the limitations?4 answersLimitations in research are openly acknowledged to maintain academic honesty and humility, serving as a source for future research ideas. In the context of experimental permeability measurements, limitations arise from systematic errors in data acquisition, optical distortions, and uncertainties in viscosity measurements, impacting measurement accuracy. In the study of nutrient limitations in the Proterozoic biosphere, phosphorus is identified as the likely globally limiting nutrient due to low nutrient demands despite increased burial efficiency. Benchmark experiments like the 1% CO2 concentration change may have limitations, as seen in the CMIP5 project, where a logistic function-derived pathway showed differences in model outputs, suggesting the need for alternative benchmark experiments in future iterations. Barriers to precision medicine implementation include high drug costs, lack of genomics knowledge among primary care physicians, and increased workload for clinicians.
What are the key factors that influence the performance comparison of databases with ORM?5 answersThe key factors that influence the performance comparison of databases with ORM include the selection of the database manager, the benchmarks used for hardware and software, the type of data being handled, and the workload conditions. The choice between SQL and NoSQL databases plays a crucial role in determining the performance of the system. Additionally, the specific features and capabilities of different database management systems can impact their performance in handling multi-model data. The type of CRUD operations performed on the database and the number of entries being processed can also affect performance. Furthermore, factors such as epoch size, load conditions, and failure conditions can influence the throughput and latency of distributed OLTP systems. Finally, the settings and parameters used in benchmarking can significantly impact the performance numbers and should be carefully considered.
What are the challenges in developing OCR for regional languages of India?4 answersDeveloping OCR for regional languages of India poses several challenges. One major challenge is the complexity of the scripts and handwriting accents available in these languages, which makes it difficult to accurately recognize the characters. Additionally, the variation in terms and ambiguity in lexical resources further complicates the task of OCR for Indian languages. Another challenge specific to Sanskrit is the lack of datasets and the presence of long-length words in classical Indic documents, which affects the word accuracy of OCR systems. Furthermore, the intricacy of characters with similar structures in languages like Telugu adds to the complexity of OCR, especially for handwritten text. Overall, OCR for regional languages of India, including Sanskrit, Tamil, and others, remains an unsolved challenge for researchers globally.
What are the challenges and limitations of multilingual text mining?5 answersMultilingual text mining faces several challenges and limitations. One major challenge is the co-existence of code-mixed text with monolingual and noisy text, making it difficult to identify and filter code-mixed content. Additionally, the unstructured and heterogeneous format of research publications poses a significant obstacle to large-scale analysis. Furthermore, the development effort required for text analysis tools in multiple languages is often substantial, limiting the application of these tools to only a few languages. Moreover, traditional tools are insufficient for extracting information from unseen data, highlighting the need for advanced frameworks that can handle big data and combine it with traditional data. These challenges and limitations underscore the need for improved code-mixing metrics, enhanced information extraction techniques for scientific text, and the availability of freely accessible multilingual resources.
First person who propuse schema?4 answersThe concept of schema was first elaborated by Bartlett in 1932and laid the foundation for the later schema theory.
