In the literature, it appears as structuring to-do items by likely completion time and co-time; abstracting analyses over time-stamped event sequences through triples \(T=\langle \text{action}, \text{data target}, \text{data criterion} \rangle\); converting a continuous stream into discrete continual-learning tasks by placing time boundaries; identifying video classes whose recognition depends on temporal order; and encoding deadline- or interval-constrained schedules for real-time, robotic, and quantum optimization systems [2111.06902] [2209.10181] [2604.21930] [1907.08340] [2602.18109] [2511.15590]. This suggests a recurring objective: to replace implicit temporal dependence with explicit temporal objects that can be annotated, benchmarked, optimized, or controlled. ## 1. Formal scope and representative abstractions Across domains, Temporal Taskification is not a single formalism but a set of domain-specific temporal encodings. In MS-LaTTE, it is the “structuring, scheduling, and bundling of tasks according to when they are likely to be completed,” using time buckets and co-time likelihoods. In time-stamped event sequences, it is the systematic definition and operationalization of tasks over sequences \(S=[(e_1,t_1),(e_2,t_2),\ldots,(e_n,t_n)]\) through triples \(T=\langle a,\tau,\kappa\rangle\). In streaming continual learning, it is the ordered partition \(\tau=(t_0,t_1,\ldots,t_K)\) that induces task intervals \(I_k^\tau:=[t_{k-1},t_k)\). In TempoNet, it is the discretization of temporal slack \(s_i(t)=(d_i^{(k)}-t)-c_i(t)\) into urgency tokens [2111.06902] [2209.10181] [2604.21930] [2602.18109]. | Domain | Formal object | Temporal role | |---|---|---| | To-do tasks | Time bucket, co-time pair label | Structuring, scheduling, bundling | | Event sequences | \(T=\langle \text{action}, \text{target}, \text{criterion} \rangle\) | Analysis task abstraction | | Continual learning | \(\tau=(t_0,\ldots,t_K)\) | Stream-to-task partition | | Video understanding | \(T(i)=A_c(i)-A_s(i)\) | Temporal dependence audit | | Real-time dispatch | \(\tilde{s}_i(t)=\mathrm{clip}(\lfloor s_i(t)/\Delta\rfloor,0,Q-1)\) | Urgency tokenization | | Interval scheduling | \(x_{ij}\in\{0,1\}\) with overlap coefficients \(c_{ik}\) | Resource-constrained assignment | The temporal object being manipulated changes with the application. For TSES, the central issue is analytic expressiveness over event order, gaps, recurrence, and metadata. For video, the issue is whether class recognition genuinely depends on chronological order. For streaming CL, the issue is whether different valid time boundaries induce different continual-learning regimes. For schedulers, the issue is whether deadlines, overlaps, or slack can be converted into tractable optimization variables [2209.10181] [1907.08340] [2604.21930] [2511.15590]. ## 2. Data-centric temporal abstraction and annotation A substantial branch of Temporal Taskification is empirical and annotation-driven. MS-LaTTE compiled aggregated logs from the now-defunct Wunderlist task app, passed through an enterprise-grade anonymization pipeline in which all personally identifiable information was removed and tasks created by fewer than five users or fewer than 100 times in total were discarded. From 12,000 sampled task–list pairs annotated in two stages, 1,899 were removed for quality control, yielding 10,101 unique task–list pairs. Time labels used 10 buckets formed by crossing Morning, Afternoon, Evening, Night, and Anytime with Weekday and Weekend; location labels included Home, Work, Public location, and Somewhere else, with a refined public taxonomy of 69 labels. Inter-annotator agreement used Krippendorff’s Alpha with MASI distance: location had \(\alpha=0.50\), improving to \(\alpha=0.87\) when singleton labels were removed, while time had \(\alpha=0.09\), improving to \(\alpha=0.26\) under the same adjustment [2111.06902]. For time-stamped event sequences, the methodology is explicitly data-centric and proceeds in five phases: data collection, coding, task categorization, task synthesis, and action–target(criterion) crosscut. The resulting typology uses 23 action categories and separates four targets—event, event sequence, group of event sequences, and metadata—from five criteria—event, event sequence, group of event sequences, metadata, and feature/metric. The reported outcome is a generalizable task set “occurring in both sources,” with 23 tasks in the shared synthesis [2209.10181]. Temporal information extraction in text follows a similar decomposition. TempEval-3 organizes temporal processing into three coordinated subtasks: TIMEX3 extraction and normalization, EVENT extraction, and TLINK relation extraction from raw text. It scales training with TimeBank (61,418 tokens), AQUAINT (33,973), TempEval-3 Silver (666,309), TempEval-3 Gold (20,000), and a 20,000-token evaluation set, while relation scoring is closure-based and graph-oriented rather than pairwise only [1206.5333]. These examples indicate that temporal taskification often begins by deciding what temporal entity is observable and annotatable: likely completion contexts, event-sequence predicates, or textual temporal mentions and relations. A plausible implication is that temporal models are only as stable as the temporal abstractions used to produce their supervision. ## 3. Benchmarks, prediction tasks, and evaluation regimes Once temporal structure is encoded, it becomes a target for prediction and benchmarking. In MS-LaTTE, co-location and co-time are binary prediction tasks over task pairs \(\mathcal{T}_1=(t_1,l_1)\) and \(\mathcal{T}_2=(t_2,l_2)\), where the label is positive if the pair shares at least one majority-agreed label. The benchmark contains 25,000 task pairs with 20,000 train, 1,000 validation, and 4,000 test instances, stratified so that tasks in one split do not appear in another. On the test set, BERT TE-FT achieved 81.98 / 0.773 for co-location and 59.10 / 0.569 for co-time, outperforming Random, Lexical, GloVe, and fixed-embedding BERT baselines; improvements over the baselines were significant at \(p=0.01\) [2111.06902]. Video temporal benchmarking uses a different audit. “Only Time Can Tell” defines a temporal dependency score \(T(i)=A_c(i)-A_s(i)\), where \(A_c(i)\) is human accuracy under ordered playback and \(A_s(i)\) is accuracy when frames are shuffled in a way that preserves per-frame content but removes motion cues. A class enters the temporal set if \(A_c(i)\ge 0.70\) and \(T(i)\ge 0.40\) for Kinetics or \(T(i)\ge 0.60\) for Something-Something, or if confusion with a temporally related counterpart exceeds 20%. The resulting Temporal-50 contains 50 temporal classes and 35,045 videos. Benchmarking showed that optical flow yields higher Temporal Score across architectures, while I3D had the best traditional accuracy but not the best temporal score [1907.08340]. Streaming continual learning makes the evaluation dependence itself part of the object of study. A taskification \(\tau\) induces adjacent discrepancy samples \(D_{\mathrm{adj}}(\tau)\), longer-range discrepancy samples \(D_{\mathrm{lr}}(\tau)\), an overall profile distance \[ D_{\mathrm{prof}}(\tau,\sigma):=\left[\alpha D_{\mathrm{pl}}(\tau,\sigma)^2+\beta D_{\mathrm{st}}(\tau,\sigma)^2\right]^{1/2}, \] and a Boundary-Profile Sensitivity \[ \mathrm{BPS}(\tau;\delta):=\mathrm{mean}_{\sigma\in N^{\mathrm{bdry}}_\delta(\tau)} D_{\mathrm{prof}}(\tau,\sigma). \] On CESNET-Timeseries24, varying only the temporal taskification across 9-, 30-, and 44-day windows materially changed average MSE, Forgetting, and BWT; the 30-day split yielded the lowest average MSE across methods, and shorter taskifications had higher BPS [2604.21930]. TimeArena extends benchmarking to language-agent multitasking under minute-resolution temporal dynamics. It evaluates Average Progress Score, Completion Speed, Task Completion Rate, and Average Completion Time on 30 real-world tasks in cooking, household activities, and laboratory work. GPT-4 reached, for example, a Task Completion Rate of 70% on two-task cooking bundles with \(CT=52.57\), 100% on two-task household bundles with \(CT=34.50\), and 50% on two-task laboratory bundles with \(CT=39.20\); Oracle shortest completion times averaged 18.9, 12.8, and 16.1 minutes for single tasks in the three domains [2402.05733]. ## 4. Scheduling, dispatch, and allocation under temporal constraints A large part of Temporal Taskification concerns turning time constraints into schedulable optimization variables. TempoNet does this by converting continuous temporal slack into discrete urgency tokens. Slack is defined as \(s_i(t)=(d_i^{(k)}-t)-c_i(t)\), quantized by \(\tilde{s}_i(t)=\mathrm{clip}(\lfloor s_i(t)/\Delta\rfloor,0,Q-1)\), and embedded as \(x_i(t)=E[\tilde{s}_i(t)]\). The scheduler couples a permutation-invariant Transformer to Deep Q-Learning, uses latency-aware sparse attention with blockwise Top-\(k\) selection and locality-sensitive chunking, and reports “Complexity is \(O(N^{1.1})\).” On industrial and large-scale settings it reports sub-millisecond inference, including 375 \(\mu s\) end-to-end at \(N=600\) on Tegra Orin Nano CPU-only, and 87.0% hit rate for quantized slack versus 79.5% for continuous slack plus MLP [2602.18109]. In fixed-schedule real-time systems, the same taskification problem is cast through arrival and service curves. The TT/ET synthesis method based on real-time calculus defines a maximal affine envelope \(\alpha^{TT}(t)=U^{TT}t+b^{TT}_{\max}\), derives \[ b^{TT}_{\max}=\min\!\left(\min_{p(i)}\Big((\lambda-U_{>p(i)})\cdot \min_{\tau_j:\,p(j)=p(i)} D_j - C^{ET}_{\ge p(i)}\Big),\, C^{TT}\right), \] and enforces it through a Burst Limiting Constraint combined with modified Least-Laxity-First scheduling. The motivating oversampling example is explicit: an ET task with \(C=2\) ms, \(D=20\) ms, \(T=100\) ms requires slots every 9 ms under naive polling, consuming \(\approx 22.2\%\) utilization despite 2% nominal utilization [2204.10264]. Online expert crowdsourcing turns macrotasks into time-indexed worker assignments. TAS introduces binary variables \(x_{ijt}\) for assigning worker \(i\) to job \(j\) at time \(t\), subject to availability, release dates, budgets, and the sequentiality constraints that a worker handles at most one job per slot and a job receives at most one worker per slot. The online algorithm constructs a daily bipartite graph over active jobs and available workers, with edge utility \[ u(i,j,d)=\frac{e_{i,k_j}}{w_{i,k_j}}, \] and solves a maximum-weight matching. In synthetic evaluation, tas-online completed 355 jobs, compared with 114 for random egoistic filter and 82 for online greedy; the offline upper bound was 515 and tas-offline completed 411 [1601.04038]. QTIS formulates interval scheduling directly as QUBO. With binary assignment variables \(x_{ij}\), overlap coefficients \(c_{ik}\), and penalty \(P=I\cdot J+1\), it minimizes \[ Q(x)=-\sum_i\sum_j x_{ij}+\sum_i P\left(\sum_j x_{ij}-1\right)^2+\sum_j\sum_{i
