How to Write a Sentence Rewriting for Computer Science

In computer science, clarity is paramount when describing complex logic, distributed systems, or algorithmic complexity. Rewriting sentences effectively ensures that technical specifications and research findings are accessible to peer reviewers and developers alike without losing mathematical precision.

What Is a Sentence Rewriting in Computer Science?

Sentence rewriting in computer science is the process of refactoring technical prose to improve readability, eliminate ambiguity in logic, and adhere to formal documentation standards. Unlike general writing, it requires maintaining the exact semantic meaning of variables, complexity notations like Big O, and specific architectural patterns while reducing cognitive load for the reader.

Before You Start

• Identify the core technical contribution (e.g., an optimization, a new protocol, or a proof).
• Define all mathematical symbols and variable names consistency (e.g., ensuring 'n' always represents the number of nodes).
• Determine the target venue's style requirements, such as the IEEE or ACM formatting guidelines.
• Clarify the specific logical relationship you are trying to convey (causality, concurrency, or sequence).

Identify and Resolve Ambiguous Pronouns

In technical descriptions, pronouns like 'it' or 'this' can often refer to multiple preceding nouns (e.g., the algorithm, the data set, or the server). Rewrite to explicitly name the subject.

Example: Original: 'The scheduler assigns the task to the processor, and it starts executing.' Rewritten: 'The scheduler assigns the task to the processor, which then begins execution.'

Tip: Always check if 'it' could refer to more than one component in a distributed system description.

Convert Passive Voice to Active for Process Flow

While some formal papers use passive voice, describing a system's action is often clearer in the active voice to show which component is performing the operation.

Example: Original: 'The packet is intercepted by the firewall.' Rewritten: 'The firewall intercepts the packet.'

Tip: Use active voice when describing the functional steps of a protocol to clarify the actor.

Eliminate Nominalizations in Algorithm Descriptions

Nominalizations (turning verbs into nouns) make sentences heavy. Use the verb form to describe the action of the code or system.

Example: Original: 'The implementation of the sorting algorithm was performed by the module.' Rewritten: 'The module implemented the sorting algorithm.'

Tip: Look for words ending in -tion or -ment and try to turn them back into active verbs.

Refine Quantitative Comparisons

Avoid vague terms like 'faster' or 'better.' Rewrite sentences to include specific metrics or comparative frameworks common in CS research.

Example: Original: 'Our neural network is much faster than the baseline.' Rewritten: 'Our neural network reduces inference latency by 30% compared to the ResNet-50 baseline.'

Tip: Always specify the baseline or control group when making performance claims.

Simplify Multi-Clause Technical Sentences

CS students often try to cram an entire logic gate or conditional flow into one sentence. Break these into logical steps.

Example: Original: 'If the buffer is full and the interrupt is triggered, the CPU halts, but if the buffer is empty, it continues.' Rewritten: 'The CPU halts if the buffer is full when an interrupt occurs. Conversely, the CPU continues processing if the buffer remains empty.'

Tip: One sentence should generally represent one logical state or transition.

Standardize Mathematical Notation Integration

Ensure that mathematical expressions are grammatically integrated into the sentence structure rather than floating as isolated fragments.

Example: Original: 'The runtime is O(n log n), this is efficient.' Rewritten: 'Because the algorithm achieves a runtime complexity of O(n log n), it is suitable for large-scale datasets.'

Tip: Treat Big O notation as an adjective or a noun phrase within the sentence.

Clarify Temporal and Causal Relationships

In concurrent programming or networking, the order of events is critical. Use precise transition words to rewrite ambiguous timelines.

Example: Original: 'The client sends a request and the database updates.' Rewritten: 'Immediately after the client sends a request, the database performs a synchronous update.'

Tip: Use words like 'simultaneously,' 'subsequently,' or 'asynchronously' to define timing.

Common Mistakes to Avoid

• Using 'since' when you mean 'because' (in CS, 'since' often implies a temporal start point).
• Anthropomorphizing software (e.g., 'The program thinks that...') instead of using functional terms.
• Overusing 'very' or 'extremely' instead of providing actual data or complexity classes.
• Failing to define acronyms (like API, REST, or FPGA) on their first mention.
• Confusing 'effect' (noun) with 'affect' (verb) when describing system impacts.

Pro Tips

• Read your pseudocode aloud alongside your descriptions to ensure the prose matches the logic.
• Use 'we' when describing the authors' contributions and 'it' or the component name when describing the system.
• Focus on the 'mechanism'—always explain how a specific optimization leads to the stated result.
• Keep the 'Subject-Verb-Object' order for maximum clarity in technical documentation.
• Use LaTeX for all mathematical symbols even within sentences to maintain professional formatting.

Frequently Asked Questions

Should I use 'I' or 'We' in a computer science paper?

In most CS publications, 'we' is preferred even for single-author papers, as it invites the reader into the logical journey. Avoid 'I' unless specifically requested by a journal like 'Nature' or 'Science' for personal perspectives.

How do I rewrite a sentence to include Big O notation?

Integrate it naturally as a property of the algorithm. Instead of saying 'The speed is O(n),' write 'The algorithm scales linearly with a time complexity of O(n).'

Can I use contractions in technical CS writing?

No, avoid contractions like 'don't' or 'can't' in formal papers, lab reports, or theses. Rewrite them as 'do not' or 'cannot' to maintain a professional tone.

How do I make my methodology section more concise?

Focus on the 'what' and 'how' by removing filler phrases like 'It is worth noting that' or 'In order to.' Start sentences directly with the action or the component involved.
