Given the sentence “在 夫子庙 入口 遍布 我 喜欢 的 小吃店”, please show the results after (a) constituency parser, (b) noun phrase chunker, and (c) dependency parser. (15 points) 2. Assume arc-standard dependency parser is adopted. Please show the actions to parse the sentence “在 夫子庙 入口 遍布 我 喜欢 的 小吃店”. (10 points) 3. Assume we have a set of four discourse relations – say, temporal, contingency, comparison, and expansion, as defined in PDTB. Please judge if ”而” in each of the following sentences is a discourse connective. If yes, please specify their relations based on the connective.

In recent years, there are important advances in the quality of state-of-the-art models, but those models are often less interpretable. Nowadays “explainable NLP”is an emerging research when we develop a model. Attention mechanism is widely used operation to enable explanations. Please explain how it achieves "explanation." (10 points) 5. Nowadays newspapers become more partisan. Some research proposes a slant index to measure the frequency of phrases to sway readers to the left or the right in a media outlet. Some research investigates demographic characteristics and political attitudes of newspaper readers in Taiwan from 1992 to 2004. Their studies conclude that media are biased, i.e., left-wing vs. right-wing in US and pan-green vs.panblue in Taiwan. Now you are asked to design an NN model to transform a pan-green content to a pan-blue one. Please show your idea. (10 points) 6. There are several ways to achieve semantic analysis. One possibility is a sequenceto-sequence model to transform an NL sentence to a semantic form. Another possibility is to extract the most important parts from an NL sentence, such as Arg0, Arg1, and so on. Please explain the ideas behind these two possible solutions. (15 points) 7. One major disadvantage of skip-gram and CBOW is the same representation for different senses of a word. Do you have any idea to capture a suitable sense of a word based on its context? (10 points) 8. To automatically interpret the semantics of written languages, the analysis and understanding of causal relationships between facts stand as a key point. The following shows three examples. The 2nd column shows a passage. The cause and the effect extracted from the passage are shown in the 3rd and 4th columns, respectively. https://imgur.com/a/GAyJN9h Assume you are given a cause-effect corpus consisting of passages with annotated cause and effect segments. You are asked to design a system to identify the cause and effect segments from the given passage. (10 points) 9. For the privacy and security issues, electronic medical records (EMRs) have to be de-identified before being released for potential applications. According to HIPPA, 18 types of identifiable data must be removed, including names, telephone, email addresses, IP addresses, social security numbers, medical record numbers, and so on. Do you have any ideas to deal with this problem? (10 points) --
