#10 Defining vs non-defining (extra information) relative clauses
One simple rule is that non-defining relative clauses, a.k.a extra information, are always distinguished from the main sentence with commas. It is easier to learn by examples, isn’t it? So here we go…
Everest which is the highest mountain in the world was not climbed until 1953.
Everest, which is the highest mountain in the world, was not climbed until 1953.
You don’t need to define which Everest. It’s just extra information about Everest.
The river that runs though Paris is called the Seine.
The river that runs through Paris, is called the Seine.
Don’t separate the subject ‘the river that runs through Paris’ and its verb with a comma.
The Pyrenees, which divide Spain from France, are often covered with snow.
The Pyrenees, that divide Spain from France, are often covered with snow.
No ‘that’ in a non-defining clause (extra information).
Could you please let us know the dates, which would suit you best?
Could you please let us know the dates which would suit you best?
Defining which dates are the subject of discussion.
The girls who worked hard were given a bonus.
The girls, who worked hard, were given a bonus.
Both possible. In the first ONLY the ones who worked hard got a bonus. In the second, all worked
hard, so all got a bonus.
And one more important rule: never use that in a non-defining relative clause (extra information)!
#11 All about paraphrasing
1. Reduced relative clauses
We conclude the paper with a brief section that summarizes our conclusions.
We conclude the paper with a brief section summarizing our conclusions.
The nurse who was hired by the doctor was very young.
The nurse hired by the doctor was very young.
The only theory which was possible did not account for all the data.
The only theory possible did not account for all the data.
However, not everything can be reduced, as shown in the following sentences…
This algorithm generates a schema which makes the translation algorithm easy to understand.
The computer is a system which is simple enough for a child to use.
Stars which are red are older than stars which are blue.
In the first sentence, the whole point of the sentence is telling us about the schema, reducing it will change the meaning. The same as in the second sentence, because ‘which is simple enough’ is the main point. In the third sentence, it’s not possible to reduce it into ‘Stars red’ as you can with ‘theory possible’.
2. Subjunctive form instead of modal verb
Formal writing style favors the usage of subjunctive form instead of modal verb (must, shall and should). Consider this sentence: “A radiation badge must be worn in the reactor control room.” We could change it into these following forms:
The company demands that a radiation badge be worn in the reactor control room. (verb)
It is required that a radiation badge be worn in the reactor control room. (passive)
It is essential that a radiation badge be worn in the reactor control room. (adjective)
There is a requirement that a radiation badge be worn in the reactor control room. (noun)
3. Participle clauses
Noun + present participle is usually used to combine two sentences or clauses, to create more compact (and sophisticated :p) writing style. Let’s see the examples…
We break the probability estimation into two parts. The first is the probability of…
We break the probability estimation into two parts, the first being the probability of…

#12 Mistake detection
Gathering all the knowledge previously explained, our last task is to spot mistakes occurring in a text. This was actually the first problem in the course exam, the second being a writing task — writing an introduction section for a given paper.
“Semantic-rich NLP has been tackled over the years from many systems that wed, with various emphases, work on semantic microtheories, representation terms, interlingua, ontologies and approaches to central problem of ambiguity resolution. While one can distinguish communities basing on a primary area of interest, real systems don’t know any such theoretical boundaries. In this paper we discuss a semantic-rich text processing environment that has become known as OntoSem, which incorporates an ontology and related resources that allow to support multi-lingual text processing (the goal of the approach has been interlingual machine translation originally). This OntoSem ontology is linked with lexicons for each of language processed, whose semantic structures represent another level of interlingual semantic representation. Among its other goals, OntoSem aims to solve the same problems of ambiguity resolution as controlled vocabularies do, but reaching over a language’s entire vocabulary. Unambiguous, language-neutral semantic representation is expressed in what we call Text-Meaning Representations (TMRs), that are automatically generated representations written in an ontology-grounded metalanguage.”
